Vertical cloth bag dust remover

Abstract

The invention discloses a vertical cloth bag dust remover which comprises a dust collector, gas filtering chambers, a flue gas input pipe, a dust remover box body and a dust discharge pipe. The vertical cloth bag dust remover is characterized in that the dust collector is welded at the bottom of the dust remover box body, the flue gas input pipe is arranged in the middle of the dust remover box body, a primary-efficiency filter screen is arranged at the bottom of the dust remover box body, a high-efficiency filter screen is arranged at the upper part of the dust remover box body, a plurality of partition plates are arranged in the dust remover box body between the high-efficiency filter screen and the primary-efficiency filter screen and divide the inside of the dust remover box body intothe plurality of gas filtering chambers, a dust removal plate is mounted in each of the gas filtering chambers, a dust removal cloth bag is connected with the upper surface of the dust removal plate,a gas outlet is formed in one side at the top of the dust remover box body, a high-pressure gas inlet is formed in the opposite side of the gas outlet and is connected with a high-pressure spray pipe,the high-pressure spray pipe is connected with a high-pressure gas storage tank, the high-pressure gas storage tank is arranged at the top of the dust remover box body, and a pulse solenoid valve isarranged on the high-pressure spray pipe.

Description

technical field [0001] The invention relates to the field of dust collectors, in particular to a vertical bag dust collector. Background technique [0002] In the field of industrial dust removal, the flue gas is directly discharged, and the dust in the flue gas will cause harm to the environment. Industrial dust collectors are usually used. Among them, the bag filter is a typical model of industrial dust collectors; the basic principle is that in a A certain number of cloth bags are set in the air filter chamber. After the dusty gas enters the air filter chamber from the air inlet, it can only drill into the cloth bag and then flow out of the air filter chamber from the opening end of the cloth bag, and the air is discharged through the air outlet. The dust cannot pass through. The surface of the bag, so the filtered gas dust is filtered out. In the current bag filter, in order to increase the amount of filtered air per unit time, the commonly used method is to increase th...

Problems solved by technology

In the current bag filter, in order to increase the amount of filtered air per unit time, the commonly used method is to increase the number of bags or increase the length of the bag, which will lead to a significant increase in the volume of the bag filter and occupy a larger use area , but in fact, in order to obtain a superior filtering effect, the air filter pores on the surface of the bag are very small. Usually, the total area of ​​the air filter pores on the surface of the bag is smaller than the cross-sectional area of ​​the bag, resulting in slow filtration efficiency and poor air filtration. The pores are easy to block, which affects the use effect of the bag, and it is inconvenient to replace and adjust, which increases the maintenance cost. It is difficult to guarantee the filtration efficiency and effect with a single filtration method, the dust removal quality is low, it is difficult to meet the use requirements, and the environmental protection performance is poor.
